Description
Exceptions defined by HttpCore should clean message strings when built to replace non-printable characters with hex values.
For example, cleaned message would appear as
[0x00]Hello[0x06][0x07][0x08][0x09][0x0a][0x0b][0x0c][0x0d][0x0e][0x0f]World
This is quite handy when diagnosing junk input from a third party.
